TE Connectivity ROX 3W Metal Oxide Resistor 330kΩ Axial

TE Connectivity ROX 3W Metal Oxide Resistor, 330kΩ is an axial leaded, through-hole resistor rated at 3W with a resistance value of 330kΩ. It is intended for high-power applications where surge and overload protection are important.

Overview

The ROX series combines a compact, space-saving design with a high power rating. The flameproof metal oxide film is deposited on a ceramic former, allowing the component to withstand overload conditions without risk of flame or mechanical damage. The resistor provides long-term stability and high surge capability, making it suitable for circuit protection roles.

Key Features

• Flameproof construction for enhanced safety
• Small size with high power rating for efficient PCB layout and design
• Long-term stability for consistent performance over time
• High surge and overload capability to protect against transient conditions
• Controlled temperature capability for predictable operation
• Solvent resistant coat and code

Applications

Typical applications include line protection, capacitor pre-charge and discharge circuits, balancing resistors, and snubber networks. The resistor operates over a temperature range of -55°C to +155°C, with a temperature coefficient of ±350ppm/°C, a voltage rating of 350V and a tolerance of ±5%, making it suitable for many general-purpose power applications.

Package and Dimensions

The component is supplied in an axial leaded package for straightforward through-hole (THT) assembly. Dimensions are width 3.3, depth 1.5 and height 4.3, and the component weighs 1 g.
